초록
Cotton fabrics was treated with persimmon juice by padding and their dyeability and functionality were assessed including antibacterial activity and deodorization ratio. The merit of padding-based dyeing was easier color reproduction over traditional hand dyeing where various colors and color fastness to light and laundering are hard to obtain. With larger number of padding, the dyed fabrics showed deeper red-yellow colors, which had low brightness and high chromatic colors. The dyed cotton fabrics had a perspiration fastness of 4~5 rating, a rubbing fastness of 3~4 rating, and a washing fastness of 4 rating,As the number of padding and exposed time to sunlight or UV light increase, the values of K/S and △E increased and the colors became much deeper gradually. The color development had completed about 70 hours exposure to UV. Among the light sources, the dyed fabrics exposed to UV light showed deeper yellow-red color than those of exposed to sunlight. The cotton fabrics treated with premordants like Al, Cr, Cu, and Sn revealed strong yellow colors, especially the fabrics treated with Fe mordant showed greenish red-yellow colors. As the padding times of dyeing with persimmon juice increased, stiffness and water repellent property were enhanced in warp and weft directions, respectively. Also, the dyed fabrics have good antibacterial activity and deodorization.
Abstract
Cotton fabrics was treated with persimmon juice by padding and their dyeability and functionality were assessed including antibacterial activity and deodorization ratio. The merit of padding-based dyeing was easier color reproduction over traditional hand dyeing where various colors and color fastness to light and laundering are hard to obtain. With larger number of padding, the dyed fabrics showed deeper red-yellow colors, which had low brightness and high chromatic colors. The dyed cotton fabrics had a perspiration fastness of 4~5 rating, a rubbing fastness of 3~4 rating, and a washing fastness of 4 rating,As the number of padding and exposed time to sunlight or UV light increase, the values of K/S and △E increased and the colors became much deeper gradually. The color development had completed about 70 hours exposure to UV. Among the light sources, the dyed fabrics exposed to UV light showed deeper yellow-red color than those of exposed to sunlight. The cotton fabrics treated with premordants like Al, Cr, Cu, and Sn revealed strong yellow colors, especially the fabrics treated with Fe mordant showed greenish red-yellow colors. As the padding times of dyeing with persimmon juice increased, stiffness and water repellent property were enhanced in warp and weft directions, respectively. Also, the dyed fabrics have good antibacterial activity and deodorization.
